Hi guys,


I'm sure you read this question a million times, still i cant find an answer.

I have a HD7870 with one HDMI one DVI and 2 MDP ports.

My monitors are connected as follows.

1 HDMI 1 DVI and 1 MPD with an amd recommended active dongle.

However, i got the same problem as i had with a passive dongle. All 3 monitors are recognized but i can only have two of them active at a time.

Am i missing any driver or so?

PS:

Setup is working when i connect my third monitor with a passive MDP->VGA dongle (from my macbook, pretty sure its a passive one).

I have been searchin for hours. But all threads i find tell me to use an active dongle which i do.

Pleaaaase help me

What is the exact Displayport converter that you use? Can you link to the page you bought it from?

Hi Kevin,

thanks for the fast reply.
I bought this one from amazon.
http://www.amazon.de/gp/product/B0041OEQA6/ref=oh_details_o01_s00_i02?ie=UTF8&psc=1
(Its in german i'm afraid ^^)
It is also listed on the amd website and the package also says that it converts the HDMI signal into an actual dp signal.

So this should be right.

According to the comments, the adapter is passive, which is why it doesn't work

Here is a true active adapter:

I already ordered another one just to try it. It is a bit strange though cause this specific model is listed on the amd site. Where did you find comments? Did u look it up on amazon uk?

Thanks for your help!

update:
Seems u're right. Everyone is complaining because it isnt active. :)

Please quickly cancel that order. The comments are filled with people stating it is passive and will not work. No matter how many you buy, it will never work.

I was reading the comments on this page:
http://www.amazon.com/gp/product/B0041OEQA6/ref=oh_deta...


What page on amd's site did you see it recommended?

The comments seems to suggest that the Star Tech one is a real active adapter; if so, then yeah, it should work.
